SPECIFICATION forming part of Letters Patent No. 527,643, dated October16, 1894.

Application filed December 22, 1893- -Serial No. 494,430. {No model.) 7

To all whom it may concern:

Be it known that I, ALF LAUBEBT WINGE, of Miles City, in the county ofCuster and State of Montana, have invented a new and Improved Wrench, ofwhich the following is a full, clear, and exact description.

The object of the invention is toprovide a new and improved wrench,which is simple and durable in construction, and arranged to permit theoperator to conveniently and quickly adjust the jaws and lock the sameinposition. 7

The invention consists of certain parts and details, and combinations ofthe same, as will be fully described hereinafter. and then pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is an edge view.of the same. Fig. 3 is a sectional side elevation with the end jawsopen. Fig. 4 is a side elevation of the end jaws arranged as a wirecutter. Fig. 5 is an edge view of the improvement with a handlesubstituted for the end jaws, the handle being in section. Fig. 6 is anenlarged sectional side elevation of the movable jaw and means forlocking the same to the stock. Fig. 7 is an enlarged sectional plan Viewof the stock on the line 7-7 of Fig. 3; and Fig. 8 is a sectional planview of part of the improvement on the line 8-8 of Fig. 4.

The improved wrench is provided with a stock A, carrying at its upperend the fixed jaw B provided at the back with downwardly extendingprongs B to form a claw hammer on. the wrench. On the stock A is fittedto slide a movable jaw O, carrying an interior plate formed with teethD, adapted to mesh in correspondingly shaped teeth A, formed at one side.of the stock A. The jaw O is provided with an upwardly projecting lug0, adapted to engage a corresponding recess in the fixed jaw B. Thepurpose of this lug is to prevent the article clamped between the jawfrom striking against and injuring the teeth A of the stock. The openingin themovable jaw O is sufliciently large to con- Veniently move the jaw0 up or down on the longitudinally in the back of the stock A. In

order to lock the Wedge E to the movable jaw 0,1 provide a spring catchF, fastenedto the outer side of the wedge E, as is plainly shown in Fig.6, the said catch being provided with a projection F adapted to engage acorrespondingly shaped recess O, formed inside of the jaw 0, so as tolock the said wedge in position in the jaw G. p

The free end of the spring catch F, is provided with a finger piece Fextending outward through the head E of the wedge E, as is plainlyillustrated in Figs. 1, 3 and 6, so that the operator by pressing thefinger piece F, can disengage the projection F from the recess 0, toslide the wedge E out of thejaw C. When the wedge is in this position,the jaw O can be conveniently moved up or down on the stock 'A, to movethe movable jaw O in engagement with the nut or other object to be takenhold of by the wrench; it being understood that the said nut is alsoengaged on the one side by the fixed jaw B.-

When the jaws B andO are in engagement with theopposite sides of thenutor other article, then the operator pushes the wedge E along the back ofthe stock A to move it into the opening of the jaw C, so as to draw thelatter to one side toward the back, to engage the teeth D with the teethA, at the same time causing the projection F to snap into the recess 0,thus looking all the parts in position.

The stock A, is preferably graduated to indicate linear measurement, asindicated in Figs. 1 and 3. The outer end of the stock A, terminates inan edge A to form a screw driver on the said stock, the sides A and A ofthis outer end being curved, as is plainly shown in Figs. 1 and 3.

sleeve I, fitted to slide on the stock and adapted to be secured thereonby a set screw 1'. On the sleeve I, are pivoted two jaws J and J, formedin their inner faces with curved edges J 2 and J adapted to engage thecurved sides A and A so as to move the jaws J and J apart at their freeends at the time the sleeve I is shifted upward on the stock A.

In order to hold the jaws J and J in position, I provide a ring K,through which extend the said jaws, and which also passes over the frontand back of the stock A, as is plainly indicated in Figs. 1 and 3. Thisring K is adapted to be secured in place on the stock A, by a suitablepin L. Now it will be seen, that by loosening the set screw I, andmoving the sleeve I upward 0n the stock A, the curved edges J and J ofthe jaws J and J, move up the similarly curved sides A and A of thestock A, so as to cause the jaws to swing apart, as is plainlyillustrated in Fig. 3, whereby the outer ends of the said jaws are moveda distance apart, corresponding to the article to be driven. When thisdistance between the outer ends of the jaws J and J is reached, thesleeve I is fastened in place by the set screw 1', and then the stock Ais manipulated by the operator in the usual manner, to turn the articlegripped.

On the jaw J, is secured a knife N, adapted to operate in conjunctionwith a fixed knife N, secured on the stock A, near the outer endthereof, as is plainly shown in Figs. 4 and 8, it being understood thatthe sleeve I is then looked in its normal lowermost position by the setscrew I, and the ring K is entirely removed from the said jaws. Now itwill be seen that by swinging the jaw J open, as shown in Fig. 4, awire, twine or other article the cutting edgesof the knives N'and N,

passing each other.

The gripping device G can be entirely dispensed with, as illustrated inFig. 5, and a. handle H substituted on the lower or outer end of thestock A. In this case the handle H is fastened in place on the stock, bythe pin L, as will be readily understood by reference to the said Fig.5.

It will be seen that the instrument above described, and shown in thedrawings, can be conveniently used for various purposes, and its severalparts can be readily adjusted by the operator, and the parts locked inplace after the article is gripped.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- A wrench, comprising a toothed stock having afixed jaw whose gripping surface extends essentially perpendicular tothe longitudinal axis of the stock, a movable jaw embracing the stockand having longitudinal sliding movement thereon, the said movable jawbeing provided with teeth adapted to mesh with those of the stock, awedge titted to slide between the movable jaw and the stock,longitudinally of the latter, to lock the movable jaw to the stock, anda spring catch under the control of the operator, and secured to thesaid wedge, the said catch having a projection adapted to engage arecess in the movable jaw, substantially as described.
